Storm-sash fastener



C. N. CARLSON STORM SASH FASTENER Filed March 1 1929 Patented Aug. 19,1930 UNITED i stares CHARLES N. CARLSON, F VIRGINIA, MINNESOTA, ASSIGNOROF FIFTY PER CENT TO PATENT, ()JFFICE CHARLES A. JOHNSON, 0F VIRGINIA,MINNESOTA' STORM-SASI-I Application filed March 1,

This invention relates to storm sash fasteners and has special referenceto a novel form of fastener in which means is provided whereby thewindow may be slightly raised or lowered without alfectingthe stormsash.

The principal object of my present inven-v tion is to provide practicaland eflicient means for accomplishing such relative movement of thewindow sash and storm sash.

Another ob eot is to provide a form of fastener which when supporting astorm sash in open position has the least susceptibility to rattling orabnormal movement.

Another object is to provide a fastener which "may be quickly and easilydetached from the window either for removing the storm sash orsupporting same in open position independently of the window.

Other objects and advantages of the invention will appear in thefollowing description thereof.

Referring now'to the accompanying drawing, forming part of thisapplication, and wherein like reference characters indicate like parts:

Figure 1 is a perspective view of a fragmental portion of a storm sashand window pairs or of like construction, in which latter event, ofcourse, one would appear-as shown in Figure 1, while the other wouldappear as shown in Figure 2.

1 represents a portion of the side of a window frame, the outermost stopbeing illustrated at 2, and the parting strip at 3, while in Figure 1the lower sash of the window is illustrated in dotted lines at 4 and inFigure 2 is shown in full lines, as the latter View is FASTENER 1929.Serial No. 343,717.

is pivotally connected as at 7 to the clip 8 fixed to the storm sash andupon its opposite end is enlarged somewhat in depth, in the upperportion of whichenlargement is fixed the laterally projecting pivotindicated at 9, which is designed to pivotally and slidably support theinnermost end of the arm within the vertically elongated slot 10 in theoutwardly extending flange ll of the angle bracket; the opposite flange12 of which is fastened directly against the outer face of the windowsash 4, as by screws or the like engageable through the slots 13 in theflange 12 of the bracket. There is also formed in this flange of thebracket intermediate of the slots 13 an elongated opening 14 by pressingoutwardly therefrom the intermediate flangelike member 15, itbeingparallel with the flange 11 and properly spaced therefrom to permitof the rounded hub like portion of the end of the bar 6 about thepivot 9passing readily therebetween in its up and down movement. The lowerextremity of the flange 12 of theangle bracket is somewhat pointed inshape and bent outwardly at right angles thereto as at 16, forming aslot 17 between the innermost terminus thereof and the lower corner ofthe flange 11', thisslot being for the reception ofthe elbow or limitingstop portion 18 of the enlarged end of the bar 6. The end face of thisstop portion of the rod or elbow is straight for direct abutment againstthe inner flat face of the flange 12 at the lower corner thereof, but isprovided with an extension or lip 19 at the lowermost corner thereofwhich overlaps the inner end of the slot 17to'insure a firmanti-rattling grip therein.

Between the stop portion 18 and the pivot 19 is formed an'arcuate slot20 partially about said pivot andcon'centric therewith for oooperativeengagement with the pin 21 fixed within the lower outer extremity of theflange 11 of the angle bracket; this engagement however only' occurringafter a predetermined outward movement of the storm sash, and

the object of which is to provide positively against any movement of thestorm sash by Wind or the like after being slightly open. It will beseen that when the two sashes are closed the bar 6 will lie in verticalposition tightly within the'corncr of the angle bracket and intermediateof the flanges 10 and 15, at which time the pin 21 will be wholly out ofengagement with the slot 20, or just at the entrance to same, and inwhich position the angle bracket is free to move vertically withoutbeing affected by the slot. Just as soon as for example the window sashis raised suffiiently to but slightly open the storm sash, the pin 21will enter the slot 20 showing that it will be impossible to raise orlower either sash without affecting the other, thus providim a positiveanti-rattling element in the device, which not only functions as suchwhen the windows are in any open relation, but also assists as such whenin their extreme open relation.

It will be noted that the lower end of the flange 15 terminatesobliquely as at 22, this being for the purpose of pro 'iding lateraladjustment of the inner end of the rod 6 so that it may be readilyremoved when desired, but only, at this particular poin that is when thelower extremity of the portion 18 is free from the slot 1?. For as'stance in the convenience of such adjustment in the event of thefastening device being installed as it were facing the window frame asshown in Figure 1 of the drawings, there is provided the notch 23 forindicating such removable position, and at which time it occurs directlyopposite the outermost edge of the flange 11 of the angle bracket.

By this construction it is evident that provision is made for the quickand convenient adjustment of the device either for installation orremoval of the storm window, and it is considered that such provisionwill in no wise jeopardize the efficiency of the device although toprovide against any possibility of the lower end of the rod 6 beingjarred out of position at this particular point of disconnection, thereis provided the catch memher 2% pivotally mounted as at 25 upon theflange 15, and which is designed to overlap the lower end of said flangewhen in its lowermost position and provide a positive stop againstlateral movement of the pivoted termini of the rod, which, of course,will have to be swung up into the position shown in Figure 2 of thedrawings before the lower end of the rod can be removed laterally.

It is to be understood that various modifications of tae embodiment hereillustrated and within the scope of the appended claims may be resortedto without departing from the spirit of the invention.

Having thus described my invention, what I claim and desire to secure byLeters Patent, is:

1. The combination with a window and storm sash therefor, of a fastenerconnecting same comprising a rod pivotally attached at one end to thestorm sash, means at the opposite end for pivotally connecting it to thewindow sash, said means comprising an angle bracket having a verticalslot in one flange thereof forming the pivotal connec tion with the rod,and means whereby the rod is separable from the bracket only'whenat apredetermined angle to said bracket.

2. The combination with a sash fastener of the class described havingone adjustable end, of an angle bracket for cooperative engagement withsaid end, and means whereby the fastener and bracket are unitable orseparable only when at a predetermined angle to each other.

3. The combination with a sash fastener of the class described havingone adjustable end, of an angle bracket for cooperative engagement withsaid end for permitting vertical mo ement of the bracket withoutmovement of the fastener, and means preventing such movement when thefastener is at an angle to the bracket.

4. The combination with a sash fastener of the class described havingone adjustable end, of an angle bracket for cooperative engagement withsaid end for permitting vertical movement of the bracket without thefastener only when they are lying substantially parallel with eachother.

. In testimony whereof I a: X my signature.
